Ultra-Narrow-Band Tunable Laserline Notch Filter (.pdf)
We report on an angularly tunable laserline notch filter from 760 to 785 nm with optical density of 5.7, 3 dB bandwidth of 9 cm-1 (0.55 nm) and greater than 80% transmission. The notch filter is a single element composed of six bonded slanted reflective holographic gratings in glass.

Multiple‐Wavelength Sagnac Loop Based Microwave Photonic Notch Filter with Low Group Delay Ripple
ABSTRACT A new multiple‐tap microwave photonic notch filter structure that can realize a flat group delay, while simultaneously obtaining a narrow notch filter response, is presented.
Narrow band infrared filters with broad field of view
The focus of this paper is narrow notch filter design.
Demonstration of narrowband notch and multi-notch filters
In this paper, we report on the development of a design and manufacturing capability that enables extremely narrow notch filters with high suppression at one or more wavelengths.
Optical Excisor Performance Limits Versus Improved Signal Detection
This is because it is assumed that the filter resolution or TW product provide sufficiently narrow notch filters so as to not significantly degrade the desired broadband signal.
Volume Bragg gratings as ultra-narrow and multiband optical filters
The ultra- narrow notch filter performance was tested in a single stage monochromator Raman systems to gain access to Raman frequencies very close to the laser line at 488, 532, 633, and 785 nm wavelengths.
All-optical tunable microwave interference suppression filter based on SOA
A narrow passband filter with negative coefficients and a broadband all-pass filter are synthesized to achieve a narrow notch filter with flat passband which can excise interference with minimal impact on the wanted signal over a wide microwave range.
Phase-Modulation-Based Loopback Scheme for Rayleigh Noise Suppression in 10-Gb/s Carrier-Distributed WDM-PONs
It should be noted that optical filtering at the OLT is also required in the previous schemes –, which is realized by either narrow notch filters or a wavelength-detuned arrayed waveguide grating (AWG).
Compact balanced UWB bandpass filter with one narrow notched band
Key to the design of the filter is the use of the narrow notched filter , as shown in Figure 3.
Comparison of gradient index and classical designs of a narrow band notch filter
In this paper three designs of a narrow notch filter centred at the wavelength of 532 nm are presented.
High-energy laser plasma diagnostic system
A narrow notch filter rejects strong plasma light, passing only the laser probing beam, which carries the plasma density information.
A modified fixed-point computational gradient descent Gray-Markel notch filter method for sinusoidal detection and attenuation
When a is close to one, the resulting very narrow notch filter that must be exactly tuned to the interference in order to get good attenuation.
Effects of Variation of the Substrate Thickness of Rectangular Slot Resonator with Multilayer
ABSTRACT: A new multiple-tap microwave photonic notch filter structure that can realize a flat group delay, while simultaneously obtain- ing a narrow notch filter response, is presented.
Considerations in the design of servo amplifiers for high-performance scanning systems
It is inappropriate to try to cancel a lower 0 wide resonance with a very narrow notch filter -the result will look like two very unattenuated resonances side by side.
Holographic gratings for astronomy: atmospheric lines suppression and tunable filter
On one side, thick VPHs can be used as narrow notch filters and their holographic nature allow them to be multiplexed on a unique substrate.
Porous silicon-based notch filters and waveguides
However, this is not a disadvantage if one aims to fabricate a narrow Notch filter , because the width of the stop-band becomes narrower when the index contrast is decreased.
